---

Overview of the Manufacturing Workflow

The creation of chemical-resistant rubber products follows a multi-stage process:

1. Raw Material Preparation
– Compounding: Natural and synthetic rubbers such as EPDM, Viton, NBR, Neoprene, and Silicone are selected based on the application’s chemical environment. These elastomers are compounded with fillers, curing agents, stabilizers, and special additives (e.g., anti-oxidants, plasticizers) to enhance chemical resistance.
– Mixing: Precision blending in specialized mixing mills or internal mixers ensures homogeneous distribution of ingredients, which is fundamental for repeatable resistance properties.

2. Shaping and Forming
– Molding: Compression molding, transfer molding, or injection molding is chosen depending on product geometry (sheets, grommets, seals, bellows, etc.). Strict control over mold temperature, pressure, and curing time guarantees proper cross-linking.
– Extrusion: For profiles, tubing, or gaskets, extrusion allows continuous shapes with consistent cross-sections. Die calibration and cooling rates are closely monitored to avoid surface or dimensional defects.

3. Curing (Vulcanization)
– Cross-linking: Vulcanization (often using sulfur, peroxides, or other agents) permanently sets the rubber’s physical and chemical characteristics. The process parameters are tailored for each compound to balance flexibility, strength, and, most importantly, chemical resistance.
– Post-curing: Some advanced compounds require secondary thermal treatment to outgas volatiles or further optimize resistance properties.

4. Finishing and Assembly
– Trimming and Surface Treatment: Flash removal, surface smoothing, or application of special coatings are performed for performance consistency, improved handling, and sometimes enhanced resistance.
– Assembly (if required): In products where metal inserts or fabric reinforcements are integrally molded, careful contamination control is enforced to prevent chemical incompatibility.
